MEWOI-LH250 Split Core Current Transformers meter
INTRODUCTION
Click to download: MEWOI-CT750, 1250, 2000, 3000 Split Core Current Transformers Specification
MEWOI-LH250 split core current transformers are designed for fast and easy installation. The split core design permits non-contact current measurements through magnetic field induction without requiring that the primary wire be taken offline and disconnected for CT installation. This method permits a safer, easy and portable current measurement. An internal precision burden resistor across the secondary winding of the CT provides a safe low voltage output and permits safe opening of the secondary |
